rollers 7. The shaft upon which is mounted the rock-lever 1S, carryingthe blade 17, is journaled in the adjustable frame, and the cam 19,which effects the requisite movements of said lever, is mounted on theshaft 16, so as to be adjustable longitudinally there-v of concurrentlywith the adjustment of the frame 10, as below described. Journaled inthis frame below the plane of the rol-1ers G and 7 is a set of rollers20, the axes of which are inclined to the horizontal at an angle ofabout fifty degrees, more or less. In this frame, beneath and parallelwith the rollers 20, is also journaled a set of rollers 21, that arepositively driven from one of the rollers 7 by a gear-train The rollers21 are geared to the rollers 20, so as to be concertedly driven thereby,one of each set of rollers being provided with a gear-wheel 23, betweenwhich is interposed a coacting idler 2l.

Above and parallel with the rollers 2O is a slotted plate 25, whoselower end is secured to a bracket 26 on the frame 10, in which the lowerends of rollers and 21 are j ou rnaled. The plane top surface of thisplate is substantia-lly tangential with the upper portion of theperiphery of a roller 27, journaled in the frame 10, parallel with andbelow the folding-rollers 7, fora purpose hereinafter appearing. Abovethe plate is a similar plate 25a, whose lower edge is also secured tothe bracket 26 and whose upper edge is adjacent to and parallel with oneof the rollers 7, and

its upper plane surface is substantially tangential to the lower portionof the periphery of the other of the rollers 7, as shown'in Figs. 3 and6.

The portion of the sheet folded by the rollers G is conveyed over andupon the inclined plate 25 and the portion folded by rollers 7 over andupon the similar superposed plate 25n in the following manner:Carrying-tapes 2S run over one of the rollers G and under the other ofsaid rollers, thence'over the roller 27 and return around idlers 20,journaled in a suitably-located bracket 30 on the frame 10. Anothersetofcarrying-tapes 31 passes around one of the rollers 7, downwardlyadjacent to the plate 25, under idlers 32, over and around idlersV 33,thence upwardly above plates 25, around idler-pulleys 34, journaled inbrackets 35 on the frame 10, then over the roller 27, and downwardlyadjacent to the upper surface of plate 25, returning over idler-pulleys36 to the said roller 7. The idler-pulleys 32, 33, and 3G are journaledin an adjustable bracket 37 on the `frame 10, as below explained.' Thusthe portion of the sheet folded by rollers G is advanced by .tapes 2Suntil its forward `edge comes between the latter and the under surfaceof the portion of tapes 31, adjacent to plate 2,5.. The latter tapesthereupon deiiect the said contiguousportion of the sheet down.-

` wardly, maintaining the saine in vcontact with the upper surface ofthe plate. The portion of the sheet folded by rollers 7 is carrieddownwardly between the plate 25a and the proximate portion of tapes 3l.When the said folded sheets are thus carriedfpositively down saidinclined plates, the sheets are suitably stopped along their forwardedges by a stopbar 38, which is bifurcated or slotted, as seen in Figs.7 and 3, one of its members being above and adjacent to the surface ofplate 25 and the other above and adjacent to the 'conipanion plate 25.The said stop-bar 3S is suitably carried by a frame 39, which isadjustably mounted on the frame 10, as hereinafter described.Projectinginwardlyfrom the stop-bar above the plates 25 25",respectively, are flanges 40, (seen in Figs. 7 and 9,) havinglongitudinal guideways 41 in their under surfaces adjacent to therespective plates, in which guideways are fitted and adapted to sliderods or bars 42. The outer ends of these bars or rods are secured (inthis instance adjustably, as hereinafter set forth) to a block L13,which is pivoted in the yoke-shaped lower portion of an arm al,projecting from the inner end of a sleeve 15 on a shaft 4G, mountedbetween arms or extensions 47 of the frame 39. Depending from the sleevei15 is an armS, von the lower or free end of which is a roller49,thatrides against a cam 50 on a shaft 51, journaled in the frame 10,parallel with the rollers 2O 21. The roller 49 is held in operativecontact with the cam through the action of a spring 52, which,encircling a rod 53 on an upwardlyextending arm 5l on the sleeve, actsagainst a collar on said rod and against a suitablydisposed lug orshoulder 55, through which the rod extends. The cam-shaft 51 is drivenfrom the rollers 21 through suitably-arran ged coacting gear-wheels 56.The speed of rotation of shaft 51 and the cam 50 thereon is so timedthat while the sheets are being carried to their position against thestop-bar 38 (between the respective portions of tapes 31 and the plates25 and 25) the roller 4!) `will be on one of the high faces of the cam,and hence the bars 42 will be retracted against the stress of the spring52, and after the sheets have been alined along the plane edge of thestopbar the roller 49 will descend into one ofthe depressions of saidcam and so permit the spring to press outwardly arm 54, thus per-f forcemoving the bars longitudinally toward the adjacent edge of the sheetsoverlying plates 25 and 25 and pushing the sheets along the stop-bar toa certain fixed and definite position of adj ustment regulated by thedepth of the impression in the cam. It will be 0bserved that the lowerportions of the flanges 40` are beveled or inclined to present to .theupper surfaces of the folded sheets as they are moved against thestop-bar thin edges 40, whichhold the folded portions of each sheetin'close contact with each other, so as to insure their uniformengagement by the pushbar and to obviate all liability of the bucklingor bending of the paper when acted upon by said bar. XVhen the sheetshave been adjusted, as above stated, the usual foldingblade 57 descendsand tucks the one upon the IOO IOS

IIO

l plate 255L within the one upon plate and the two into the bite offolding-rollers' 20, by which they are again and finally folded. Thisfolding-blade is carried by an arm 58, projecting upwardly from a shaft59, j ournaled in'frame 10, parallel to and above shaft 51. An arm-60,depending from shaft 59, carries at its 'free end aroller 61, whichimpinges against a cam 62 on the shaft 51, which cam in its rotationeffects the actuation of thefolding-blade to tuck the sheets into thebite of rollers 20, in well-known manner. l

Supported in the yoke-shaped lowerend of the frame 10 is the usualvertically-adjustable packingtrough 63. In this instance the trough issupported upon verticalthreaded rods 64, passing through nuts 65, heldin the frame. These nuts are connected by a chain 66, geared withsprocket-wheels 67 on said nuts, one of the latter being provided with ahand-wheel 68, which when rotated turns the nuts and effects thereby theraising or lowering of the packing-trough, as may be desired. The sheetsfolded by rollers 20'pass between rollers 21 and are discharged therebyinto the 4packing-trough, where they are packed in the usual way. Thelatter rollers insure a closer fold ofthe sheets as they passtherebetween.

In order that the frame 10 may be adjusted laterally across the machineto bring the roll- 'ers `7' -nearer to or farther from the rollers 6,

as may be required to suit different sizesheets to be folded withoutaecting the working of the other parts of the machine, I employ therfollowing mechanism: yThe frame 10 is provided at-its upper end at itsrespective sides with lugs or brackets 69, thatv fit over and.

slide longitudinally along a trackway consisting of T-rails 70,-secured,to the main ,framel andextendi-'ng across the machine in a plane atright angles to the axes of the rollers 6 andl 7. -Journaled in bearingsin the main framev `which engagelike gears=75 o n a transverse shaft 76,* having its bearings in the main frame, the lattershaft beingprovided with a crank 77 for rotating the same. If this crank beproperly turned, the shaft 7l will vbe rotated and the threadedlugs 73thereon will be moved in either direction along said shafts, thussliding'the frame 10( and' the parts carried thereby toward or away fromtherollers 6, as desired. The cam 19 is so mounted 'on the I shaft 16and connectedv with the said frame as` to partake of the adjustments ofthe latter, and thereby Aremain in engagement' with the roller onthe'lower-end of the arm lS-that is to say,- the cam is splined on asleeve78 on the shaft and'is connected by means of a yoke 79 with ltheframe 10. This spline is, as usual, spirally set-in order to in;

sure-the requisite timingof the cam in re-y spect to its coperatingparts, when said-cam is longitudinally adjusted 'on its shaft, as-j ustdescribed. The gear 11, previouslyreferred to, is mounted on its shaft 2correspondingly with the cam 19, so as likewise to partake of theadjustments of the frame 10, the yoke connection being indicated at 8O.-Inasmuch as the rollers 29 and roller 27 over which pass they tapes 28are carried bythe frame 10 these tapes will remain taut at any positionlof adjustment of said frame.

As it'is desirable that the stop-bar 38, together with the sidepusher-bars 42 andthe mechanism for .actuating the latter may beadjustable along plates 25 25, parallel with the path of movement of theincoming sheets to suit smaller or larger sheets to be folded, the frame39 upon which said stop-bar, &c., are mounted has a dovetailedbase 81',which rests in and is adapted to slide longitudinally in acorrespondingly-grooved trackway in a lug 82, secured to 'frame '10.Said lug is tapped for the reception of thethreaded shaft 83, whoseouter end is j ournaled in a lug 84 of the frame 39 and is provided witha hand-wheel? '4 85,whereby said shaft may be rotated and the IOO 86, asseen in Fig. 5, to permit the foldingp blade to reciprocate therein atany position of adjustment of the said bar.

As it is desirable that the side adjustingbars 42V may be longitudinallyadjustable in their respective guideways 41, I secure the said rods tothe block 43 in such manner that they may be independently so adjusted.To

IOS

this end the block 43 is provided in its upper and lower surfaces,respectively, with longitndinal dovetaile'd grooves, in which vareladapted to slide the`outer dovetailed ends 42aiof said bars. itsouterend a lug 87, in which is mounteda thumb-screw 88, whoseinner orthreadedfend Each of these bars has'at IIO is'screwed into'the body ofthe block 43.' By

properly turning the thumb-screws, or either of-them,'the' bars 42, foreither of'them,1may A be adjusted upon the' block 43, and ,thereby theextent of inward reciprocation of the bars 42 by the action of thespring and cam may be nicely regulated.

p It is sometimes desirable to slightly4 adj ust the stop-bar 38`inIafplane parallel with the incoming sheets to t'rue the'forward edges'ofthe latter. I therefore'pivot thestop-bar'at one endto'the frame 39 bymeans of a pin 89,

and at some distance forward of the pivot .I provide oppositely disposedadjusting thumb-screws;- 90, whichpiercel threaded lugs l91 of thestop-barand beanagains't the ppo` C on the frame. 'loadj ust thestop-bar 38-in either direction, one offsaidithurnb-screwsis l turned toretract its inner end from the lug 92, and the other screw being screwedup pushes and so adjusts the bar on its pivot until the inner end of theopposing screw again impinges against lug 92. This latter adjustment isso slight that it does not materially interfere with the reciprocationsof the bars 42 in their guideways in the bar 3S.
